ABSTRACT
This study was carried out to determine the concentration of some minerals in cows with retained fetal membranes (RFM) and to compare it with cows without RFM in Bahri locality, Khartoum, Sudan. This area contains a large number of dairy farms. A total of 60 cows (30 with retained fetal membranes and 30 without retained fetal membranes) were included. Data regarding the age, number of parities, and frequency of RFM were obtained during the visits to the farms. Blood samples were collected from jugular veins of these cows 12 to 24 hours after parturition. The estimation of serum Calcium, Iron and Phosphorus were done by using the spectrophotometric method, while Zinc was measured using Atomic absorption spectrophotometer. The mean values were compared using paired sample t test. Most visited farms reported having cases of RFM. The results showed that 63% of cows had retained placenta once, 28% had retained placenta twice and 8% had it three times. The mean values of Iron and Zinc were (83.70 ± 2.53mg/dl), (0.25±0.03 mg/dl) consecutively and were significantly lower in cows with RFM than cows without RFM (86.1± 2.91 mg/dl), (0.28±.03 mg/dl) at 12 to 24 hour after parturition. There was no significant difference between the mean value of Calcium and Phosphorus in RFM and Non RFM cows. In conclusion, minerals deficiency such as, iron, and zinc may be predisposing factor for the occurrence of retention of placenta in crossbred cattle. Maintaining an adequate dietary source of the minerals at the end of the pregnancy period is recommended.
